lt has been obtained bead of calcium alginate with micro-particles of algae Lessonia Trabeculata. The optimum pH for adsorption of Cu(II) lie between 4.5 and 5. From the study of the kinetics of adsorption was determined that the thermodynamic equilibrium was reached alter 500min. The adsorption data fitted well with the Langmuir model and showed the maximum adsorption capacity q max =14,66mg/g.

The study consists of the treatment of the pumping water of fish flour industry. The addition oí microorganisms in presence of ferric sulphate is managed to destabilize the system, obtainig that a watery solution "drains" towards the inferior part, floating solid free water particles. This behavior probably is due to the destruction of the substances that are in the different interphases when they are consumed by the microorganisms. The ferric sulfato, besides to give average acid for the reproduction of the microorganisms also contributes positive charges to the system which interacts with the acuatic system.
